I'm sorry about your last job. There is nothing worse than a toxic work environment. Congrats on the new job. How will you get to work if DH has the car, or will you be WFH? Is there no public transport to get to the nearest town?
Here are just some ideas I'd do if I had some weeks off:
-Go through each kitchen cupboard and clear out very old food, re-arrange and re-organise
-As above for a deep freeze if applicable
-Clear wardrobes and bedrooms of additional things you don't use and either throw, donate to charity or put on next door/market place
-Re-paint your bedroom, bathrooms, lounge
-Each week, get a bus/train somewhere different. Either a nearby town or a larger city somewhere, but visit the local museum/s, park, have a coffee etc
-Do online questionnaires for money. Its not alot, but I sometimes do this when watching TV.
-Learn a new craft. Quilting, crochet, knitting
-Do some fitness. Walking, online yoga or chair yoga, pilates
-Pick a new cuisine each week- Somali, Cambodian, Sri Lankan or buy a new vegetable and then find a recipe to use it in
-Read a book
-Duolingo
-Research your next holiday destination
-Start off vegetable seeds and prep garden beds
-free mahjong online
-If you can get to your local town, there are often daytime activity things, chess, cards, luncheon clubs, WI, gardening group, walking clubs, swimming club etc
